' Application filed Novemberl l, 1921fser ia1 No. 514,940.

To aZZ whom-it may concern.

Be it known that I, Moa'roN 'IIOMER lVlAGiE, a citizen of the UnitedStates, re-

siding at Los 'Angeles, in the county of Les 5 Angeles and StateofCalifornia, have invented a new and useful Tool- Feeding MeansforDrillingRigs of which the following is a specification.

This application is, in some respectsa 10 continuation of my applicationfor a patent on a temper-screw; SerialNoAtOLQM, filed August ith. 1920,and allowed 'May 16th, 1921 and involves improvements on saidapplication in which the drilling line'isf perated by achain drivenworm-gear arrangementi .Y

used in well drilling rigs having a walking beam for operating thetools.

In the art as heretofore practiced, the tool carrying end of thewalking-beam when in position for operating the toolsQhas averpendici'ilar motion of fror n two to four feet; and when the engineend otsuch beam is down or? of the crank pin, thus raising; the workingend of the beam, the up and down movement may be four or five feet, moreOr less. with lateral movement in the neighborhood of two feet,for-withdrawing the temper-screw from over the 'llOlGyiIO- ward theSamson post to ,QIVG clearance for other operations in'the hole. f

In present practice and in said applica-f tion, the drilling clampswhich carry the two links that are suspended from the two ends of a yokeor swivel that is connectedv to the bottom of the temper-screw, or thequently causes the line to strike the side of the casing, thus tendingto wear both the line and the casing," and in addition to this creates adisagreeable vibration and a jerky drilling mechanism; and the resultinglateral strain sometimes causes breakage of the temper-screw. Y i

, quired to turn the temper-screw and to feed drilling;- line and toolsare suspended by.

sitive feeling that the driller needs'to note operation which isinjurious to the rig and "same less energy of bothc'engine' and-driller,

and will reduce the't me-andefi'ort of get} In operatingline 'tOOlS, hedriller is a; I

55. the tools into the hole as the hole is'drilled; and this requiresthe use of a three decked stool. commonly; v all d th d i n knowledgebench so thatat the'jbeginningf of the operation, he can stand on theupper deck to turn the cross-bar of 'thetemper" screw, and as thedrilling proceedsandisaid L cross-bar lowerspgthe driller ca take'fs'uccessively lower decks until hefcan; operate. from the floor; 77 U Whenthe temper-sorewlhas thus been lowered, it is necessaryto'move it backupthe line to the former startingpositionfrela tive to the beam. 1 Theinvention relates to the mechanism' In order to do this the slack oftheline is t 7 taken up by the bull-wheehthus*support- I ing thetools'fr om'the'crown pulley; then the temper-screw is unclamped fromthe lineandzelevatedto' its it'ormenposition; after which it isagain clamped tothefline," the bull-wheelreleased and the line abovethe clamp given thenecessary slack and then the work proceeds as before. With presentpractice a heavy counterweight is employed to assist in returning thetemper-screw to its elevated position? and said counterweightis'attached to and I has to be carried up and downby the walking-bam ateach stroke," Such"'cimnter; weight adds to the expensejof the drillingrig and to the expense ofinstallation; and also adds additional strainto the woi'king'" parts and additional load tofbe carried by thewalking-beam bearing "and by-the engine; and also when running the rigrap,- idly, 'it causes the temper-screwfto "jump 1 from its bearingsthus adding wear and danger of breakage {it also causes excessivevlbratlon. It also interferes 'wlth the sen in, order todetermine theexact conditions *to' be met at the bottom of the hole.

' Fiu-thermore' the operation of lifting the temper-"crew in the'lnescntpractice requires the attendance of, and isdiiiicult work'for, two men.1' i Anobject of this invention is "to provide means whereby theoperation of thedrilling rig willbe more even and steady: will con vting the ,temper screw back from the lower position to the startingposition, and will also allow the temper-screw to be lowered 'more orless danger of accident on account ofthe heavy load, necessary to beliftedin shifting the position of the jars; and an object of thisinvention'is to make-provision whereby the raising or lowering of thetools or jars can be accomplished practically by one operator.

Anobject is to provide superior means for dispensing with the multipledeck stool necessary with the present, practice. The invention i broadlynew, pioneer in that'Iuse a worm rack for suspending, raising, andlowering the tools.

Ifhave so constructed the appliancethat the temper-screw for handlingthe-tools is of an endless screw construction and acts on a worm rack;and furthermore, in that provision is made for unshipping the worm andhandling the worm'rack by a pinion for rapidly raising and lowering theworm rack when the tools are suspended from the derrick. v d

An object is to weight of the tools avoid all danger of the caus ng thetemper-screw to spin, and the tools to get away vtrom the driller; andalso to avoid the necessity of alternately tightening and loosening theset screw heretofore provided to. prevent such spinning of thetemper-screw and falling of the tools.

Other objects, advantages, and features of invention may appear theaccompanying drawings, the subj oined, detail description, and theappended claims.

The accompanying drawings illustrate the invention.

In the drawings B indicates the bullwheel; the Samson 30st; W, thewalkingbeam; C, the crank; thepitinan; andD the derrick, all of whichareof the usual construction.

R is a rack bar from which the line is suspended. The rack bar is supprted by an endless screw or worm 1.

Fig. 10 is a view analogous to Fig. 9,

In carryingout this invention I construct the temper-screw in the formof a rack supporting and operating worm 1, a worm rack 52 meshingtherewith, reins 3 supporting the worm and journaled on a top bearing 4which may be variously constructed and is shown in the drawings as ashaft upon which a box 5 carried by the reins 3 is swung;

and the worm is revolved by a worm gear 6, and. its driving worm 7; saiddrivingworm is mounted on a shaft 8 drivenby a pulley or sprocket wheel9and endless'chain 10 which depends nearly to the floor 11 upon whichthe workman stands to operate the teinper-screw.

The worm rack forms a vertically mow,

able bail support and is provided at its lower end with a centrallyarranged bail bearing 12 from which is hung a single bail l3 having acentral bearing 14: to rest on said bail bearing; the top hearing at ,4,5, and the bail bearings being practically alined vertically. A.suitable clamp 15 is provided to forming a bracket attached to thebottom oi the reins 8. j

1A spur rack 19 is fixed to andextends along the worm rack 2, and apinion 20 thereforis fixed to the shaft 8, and the parts are so spacedthat the rackbar R provided with the spur rack and the worm rack may,

be operated alternately by the worm 1 and the pinion 20. a

zontal transversely shifting yokes 22, 23 which are arranged at the topand bottom of the frame 18 and are :"provided with vertical guides 24for the worm rack.

Said yokes 22, 23 are connectedtogether by the horizontal shiftingscrews 25, 26, the

driven sprocket wheel 27, sprocket chain 28 by the crank 30. a

ing yokes horizontal y so that by turning the crank 30 the worm rackwill be unshipped from the worm land the spur rack 19 will be meshedwith the pinion 20. I T

The worm 1 and the pinion 19 are both operated by the endless chain, 10over sprocket wheel 9, and the endless chain is prevented from jumpingofl? by-the' house ing .31. a

The worm 7 is revolved by the shaftiS that is revolved by endless chain10 to oper-Y ate the worm gear 6 which revolves the worm 1.

When the worm 1 is in engagement with the worm rack, the operation oftheichain will raise and lower the rack with power; and in drilling, theworm will support the tools at the predetermined depth relative to thebearing 4, except when the chain 10 is.

operated to raise orlower the tools.- When the chain is not being runthe worm rack 2 is locked and will support the tools at a. predetermineddepth and the chain under the operators hand will-give the operator thetouch or feeling necessaryto determine, the condition of the work at thebottom of the hole, and the driller will move the 'chain 10 to lower thetools as'the work proceeds.

When the tools are suspended by theline v 16 from bull-wheel shaft 32over crown pulley, not shown, as indicated in Fig. 3, the

against such action, a s ring operated thumb ratchet 33 is provide toengage the spur rack "19to prevent descent of the worm rack and to alloweasy ascent of the same when thepinion isoperatedfor that purpose. 1 1

When it is desired to lower the worm a rack, the thumb ratchet willbedisengaged- I .i

by. the operator, a'ndthe chain operated to lower said worm rack.

By the arrangement above described, whenever the tools are supported bythe worm rack, the line hangs vertically and the thrust of a thewalkingbeam. does not. cause the line to vibrate and whip the sides'ofthe hole, and the operator has easy control of the tools. .-Thesensitiveness of the endless Y chain 10 to the operation at'the bottomof, '80 posestas with the ordinary temper-screw. and driving sprocketwheel 29, all operated the hole is as complete for all practical purgThe operator can 'manipulate' the *tools i while standing on the floorthroughout all Power applied by the crank 30 will simul-' taneously andequall slide both of the shift-' positions of-the clamp 15.
